ADVERTISING DEVICE.

ARTHUR-S. LEUPOLD, or MONTREAL, QUEBEC, CANADA.

ADVERTISING DEVICE To all whom it may concern:

Be it known that I, ARTHUR S. LEU,POLD,.. of the city of Montreal, in the Province of Quebec and Dominion of Canada, have invented certain new and useful Improvements in Advertising Devices, of whichthe following is a full, clear, and exact description. v

My invention relates to improvements in advertising devices and its object is to produce a comparatively inexpensive illuminated sign in which the advertlsing matter, while stationary, has the appearance of being in constantmotion to a passer by. r i

A further object is to provide a sign which may be illuminated by sunlight during the day to roduce the same effect as when arti fiq ilally illuminated at night.

o accomplish these objects, I provide a casing having an opa ue or stained glass front on wh1ch the a vertisement is trayed transparently or translucently. ithin the casing is a frame containing a number of risms or slides of colored glass adapted to dieflect rays of colored light through the advertisement. One or more lam s backed by Q a suitable reflector illuminate t e device at a night, while a trans arent glass to and back permit sunlight to s ine onto and t rough the prisms during the day. The illusion of mo-r tion of the advertisement is due to the'con-a stantly changing angle at which a asser by views the sign, thereby bringing ifferently,

vention:Figur 1 is a pers ective view of the device with-one of the si es of t'he'casin'g; removed to show the arrangement ofthei n-t, terior. Fig. 2 is a vertical sectional viewthrough the device from front to back,- *Fi 3 is a view similar to Fig. 2 but shows an a ternative form ada ted for overhead use.

In the above do ed figures, 1 designates a casing (provided with afront 2 of opa 'ue or staine sign 4 of an advertisement ap ear transparently. A rack or frame 5 is situated behind the glass front 2 and preferably at an angle thereto, and contains a number of prisms or slides 6 of colored or stained lass, referably arranged in. rows vertica an horizontally, and secured to the rac by' mea'ns of screws 7, or any other suitable means. The rack is 'su orted in positionh any suitable form of rackets 8.. A plura ity of i Specification of Letters Patent.

. comprising a casing, an opa lam s- 9, preferably electric, are located Patented il'uly 28,- 1908.

along the u per back edge of the casing and are backed y a suitable reflector 10 adapted to concentrate their light on the prisms 6. Thelamps and reflector are carried by a frame 11 mounted on brackets or guide's'12. Panes of transparent glass 13 and 14 are placed in the top and back of the casing respectively, in or or to admit sunlight during t e day to shine through the prisms 6 and illuminate the advertisement.

The construction shown in Fig. 3, is adaptedto signs which require to be placed at a considerable height and only differs from the form shown in Figs. 1 and 2 in the position of the front 2 which is at an angle to the back of the casing and parallel to the prism frame 5. In this form of construction the prisms 6 may be replaced by plain slides 1.5" since the light rays require no deflector.

It will be obvious that this device will pro; vide a very ineX ensive and attractive advertising sign, the letters of which to a passerby will appear in motion on account of the constantly changing light passing therethrough from the colored prisms.

Having thus described my invention what I claim is 2-- 1. A device of the character described comprising a casing, an opaque front therefor havin a sign in transparent characters, a 'lurality of prisms of colored glass located ehind said front, and means for illuminating the transparent characters through said,

prisms.

2 A device of the character described comprising a casing, an opaque'front therefor lhavlng a SlgIl trans arent aframe located be ind said front and at an angle thereto, a plurality of prisms of colored glass in'said frame, andmeans for illuminating said'sign through the prisms.

3. A device of the character described avlng a sign depleted thereon, a source of light within said casing, a frame located belnnd said opa ue front and at an angle thereto, a plura ity of prisms'of colored glass arranged invertical and horizontal rows in said frame, and a reflector behind said source of ligh't adapted to project the light-through said prisms to the front of the casing.

4. 'A device of the character described ue front therefor having a sign transparent epicted thereon,
